Detailed Description

This load is applied on a specific point within the system.

The point is defined as a point within an element object.

You must provide a pointer to an element object and a number of point on which on which the load acts. Force vector F should have element->GetNumberOfDegreesOfFreedomPerNode() dimensions.

Member Function Documentation

virtual int itk::fem::LoadNode::ClassID ( ) const [inline, virtual]

Virtual function to access the class ID

Implements itk::fem::FEMLightObject.

Definition at line 38 of file itkFEMLoadNode.h.

virtual Baseclass::Pointer itk::fem::LoadNode::Clone ( ) const [virtual]

Create a new object from the existing one

Implements itk::fem::FEMLightObject.

static FEMLightObject::Pointer itk::fem::FEMLightObject::CreateFromStream	(	std::istream &	f,
		void *	info
	)			`[static, inherited]`

Read object of any derived type from stream.

This static function creates an object of a class, which is derived from FEMLightObject. The class of object is first determined from the stream, then the object of that class is constructed using the FEMObjectFactory. Finally the data for this object is read from the stream, by calling the Read() member function.

virtual Solution::ConstPointer itk::fem::Load::GetSolution ( ) [inline, virtual, inherited]

Sets the pointer to solution vector. This function is automatically called by the Solver class on every load object.

Some types of external Loads may need access to previous values of solution vector. If a derived class needs that, it should implement this function, and store the passed pointer accordingly. If the result vector is not required, the functionn should be left unimplemented, so that only the dummy implementation in base class is called.

Parameters:

ptr

Pointer to the object of Solution class.

Reimplemented in itk::fem::FiniteDifferenceFunctionLoad< TMoving, TFixed >, itk::fem::ImageMetricLoad< TMoving, TFixed >, and itk::fem::LoadLandmark.

Definition at line 57 of file itkFEMLoadBase.h.

static Self::Pointer itk::fem::LoadNode::New ( void ) [inline, static]

Object creation in an itk compatible way

Definition at line 38 of file itkFEMLoadNode.h.

virtual void itk::fem::LoadNode::Read	(	std::istream &	f,
		void *	info
	)			`[virtual]`

Read a LoadNode object from input stream.

Reimplemented from itk::fem::FEMLightObject.

virtual void itk::fem::Load::SetSolution ( Solution::ConstPointer ) [inline, virtual, inherited]

Sets the pointer to solution vector. This function is automatically called by the Solver class on every load object.

Some types of external Loads may need access to previous values of solution vector. If a derived class needs that, it should implement this function, and store the passed pointer accordingly. If the result vector is not required, the functionn should be left unimplemented, so that only the dummy implementation in base class is called.

Parameters:

ptr

Pointer to the object of Solution class.

Reimplemented in itk::fem::FiniteDifferenceFunctionLoad< TMoving, TFixed >, itk::fem::ImageMetricLoad< TMoving, TFixed >, and itk::fem::LoadLandmark.

Definition at line 56 of file itkFEMLoadBase.h.

static void itk::fem::FEMLightObject::SkipWhiteSpace ( std::istream & f ) [static, inherited]

Helper function that skips all the whitespace and comments in an input stream.

virtual void itk::fem::LoadNode::Write ( std::ostream & f ) const [virtual]

Write a Load object to the output stream

Reimplemented from itk::fem::FEMLightObject.

Class ID for FEM object factory

Definition at line 38 of file itkFEMLoadNode.h.

vnl_vector<Float> itk::fem::LoadNode::F

int itk::fem::FEMLightObject::GN [inherited]

Global number of an object (ID of an object) In general the ID's are required to be unique only within a specific type of derived classes (Elements, Nodes, ...) If the GN is not required, it can be ignored. (normally you need the GN when writing or reading objects to/from stream.
